- A water pipe has a 3.0 cm inside diameter and carries water into the basement of a house. At the basement, the water speed is 1.20 ms−1 and the pressure exerted is 190 kPa. The pipe then tapers to 1.5 cm inside diameter as it rises to the second floor, which is 8.5 m above the input point. Calculate: a) the speed of the water on the second floor.b) the water pressure on the second floor2. Water flows through a fire hose of diameter 6.35 cm at a rate of 0.012 m³/s. The fire hose ends in a nozzle of inner diameter 2.20 cm. What is the speed with which the water exits the nozzle?solve the problem below
- A U-shaped tube is filled with water until the liquid level reaches B=36 cm above the bottom of the tube, as shown in the figure below. The areas of the two arms of the tube are equal. An oil, which has a density 90% of the density of water, is now poured into one arm of the U-tube until the water level in the other arm of the tube reaches A = 42 cm above the bottom of the tube. Calculate the height H of the oil column and mark the alternative that is closest to the value found. Choose the correct alternative: a) 20/3 m b) 9/2 m c) 40/3 m d) 9 mrn=0.17 cm (nozzle radius)rh=0.95 cm (garden hose radius)Q=0.65 L/s (flow rate through the hose) Calculate the maximum height (in centimeters) to which water could be squirted with the hose if it emerges with the nozzle removed, assuming the same flow rate.Solve
